ANTl-FRICTION JOURNAL.

SPECIFICATION forming part of Letters Patent No. 422,903, dated March11, 1890.

Application filed .I une 14, 1889. Serial No. 314,220. (No model.)

To all whom it may concern."

Be it known thatLBEUNo BEAUPEE, of St.

Paul, in the county of Ramsey and State of Minnesota, haveinventedcertain new and useful Improvements in Anti-Friction Journals 5 and I dohereby declare the following to be a full, clear, and exact descriptionof the same, reference being had to the accompanying drawings, forming apart of this specilication, and to the iigures and letters of referencemarked thereon.

This invention relates to that class of antifriction bearings in whichthere is combined a series of bearing-rollers co-operating with theshaft and a series of separating-rollers arranged between thebearing-rollers and inner and outer connected rings, with which thejournals of thebearing-rollers and the journals of the separatingrollersrespectively cooperate; and it consists in certain improved details ofconstruction, which willbe hereinafter described, and pointed outparticularly in the clauses of claims at the end of this specilication.

In the accompanying drawings, Figure l is an end elevation of a bearingconstructed in accordance with my invention. Fig. 2 is a sectional viewon the line c; 4r, Fig. 1. Fig. 3 is a perspective view of one set ofthe retaining-rings. Fio. 4 is a section on the line yy, Fig. 2.

Similar letters of reference in the several figuresindicate the sameparts.

On the shaft A are preferably arranged two collars A A', between whichrun the bearingrrollers B, the casing C and separating-rollers D beingarranged outside the bearing-rollers in the ordinary well-known manner.At each end of the bearing-rollers and separatingrollers are formedjournals E E', preferably ot' somewhat reduced diameter, against whichthe retaining-rings are adapted to bear. Said rings F and G arepreferably two in number at each end, connected rigidly together` theinner one F fitting inside of and taking its bearing against thejournals E of the bearing-rollers, and the outer one Glying outside ofand taking its bearing against the journals E of thesepaIati11gIolleI-s, thus coniining all the journals Within the comparatively limited space between the two rings, with which construction itwill be seen that the bearing-rollers only come in contact with theperiphery of the inner ring, and as they all travel in one directionwill tend to move said ring in one direction, and that theseparating-rollers come in contact only with the inner surface of theouter ring, and as they all move in the sain'e direction will tend tomove said ring in but one direction also; but as said separating-rollersrotate on their axis in the opposite direction from the bearing-rollers,the two rings are caused to travel in the same direction. Thus byproperly proportion ing t-he size of thev rollers and journals allfriction on either ring is overcome, the bearing-surfaces in everyinstance making rolling contact only. Although said rings may be made inone piece, they are preferably separate, as before mentioned, andconnected by removable cross-pieces or segments H, which pass outside ofthe journals on the rollers, as clearly indicated in Fi. l.

For the sake of convenience in the manufacture and efficiency in therunning of the bearing, each of said rings is preferably provided nearthe outer edge with a groove or cut-away portion, as at f g, in whichare adapted to run small disks or plates I, preferably removably securedon the ends of the rollerjournals by Ineans of screws c', therebyVretainin g the rings in position on the journals and permitting thesame to be removed or applied after the rollers are put in position, thespaces between the segments H permitting the screws i to be readilyremoved lor inserted. As an additional security against lateral motionof the rollers, they may be provided with central grooves, in whichworks a projection or rib M, formed upon or secured to the inner side ofthe casing, and, if desired, instead of employing two collars on theshaft, one at each side of the roller, a single collar may be arrangedthereon and adapted to work in the groove of the bearing-rollers, asindicated in dotted lines, Fig. e.

By connecting the two retaining-rings rigidly together, as described, itwill be seen that an exceedingly strong and rigid structure is formed,and as such rings are employed at each end of the bearing there is noliability or chance of the rollers being misplaced or getting out oftheir relative positions, so as to produce undue friction or grind, tendIOO .the shaft A, `of the collars A A', secured thereon, the series ofbearing-rollers B, bearing` between the collars, the series ofseparating-rollers D, and the connected inner and outer rings F G, allconstructed and arranged substantially as described.

-zo 2. Ina roller-bearing, the combination of the series otbearing-rollers and the series of separating-rollers with the connectedinner and outer rings, grooved or cut away, as at f g, and the disks orplates I, removably secured to the ends of the roller-journals andprojectinginto the said grooves or cut-away portions, whereby the ringsare retained in position on the roller-journals, and whereby also therings are enabled to be removed or applied after the rollers are placedin position without disturbing the rollers, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.
